Possible coolant leak?

Good morning. I can smell coolant, especially when it's running idle, but I don't see coolant coming out. It also looks like there may be a little spatter of coolant under the hood, but I'm not sure if that's from my husband spilling when he adds coolant or if it's spraying from someplace. I think there may also be an oil leak because I've had to add engine oil at least every other week. Does this seem like an urgent, needs immediate resolve problem?
